Title: Limiting production rates in C-steel pipes. Removal of inhibitors/corrosion products by fatigue/yield action of liquid or gas/liquid

Abstract

The objective of this paper has been to form a link between the limiting production rates and the strength of the corrosion product formed on carbon steel. This paper has studied the available experimental data related to the failure of corrosion products with and without strengthening by inhibitors. Corrosion products in smooth pipes, bends and weldlike obstacles have been investigated. A model has been developed based on these observations which connects the strength of the corrosion product with the wall shear stress in both liquid and multiphase flow. Given the chemistry, temperature and metallurgy of the material the model allows the transformation from simple liquid tests to different flow conditions in the field. Thus limiting production rates in a field can be determined based on simple model tests. Relationships for the wall shear stress amplitudes, frequencies and mean values for various flow regimes have been developed. These relations are required in the model simulating the strength of the corrosion product. The paper shows why bends and weldlike obstacles constitute exposed areas. This study is the first of its kind. Thus the models developed lack detailed experimental verifications. The paper therefore briefly describes further work which has been initiated in ordermore » to verify the hypothesis formed.« less
